For those that don't know this method you put a penny near the top of both front tires in the same location on each side. You then slowly lift the front of the car with a sharp knife and the first penny that falls indicates that side to be light. You then adjust untill both pennies fall at the same time. This works extremely well with any 2 wheel drive vehicle especially 12th scale.
Do you tweak your 12th scale only testing the front? What about the rear?
